t Application filed March 23.1925. Serial No. 17,745. l

To all whom z't-mrty/ con-cern.'

Be it known that I, MAnroN RUBLE, a citizen of the United States, residing at Portland, vin the county of Multnomah and State of Oregon, have invented new and useful Improvements in Cutters, of which the following is a specification.

My invention relates to wood working cutting knives or blades associated there-- with which are associated with the cutter heads in a novel manner so that they can be 1geadily removed from the heads for the purposeV of sharpening or inserting new blades. l

lVith the preceding and other objects and advantages in mind, the invention consists struction and arrangement of parts and opera-tions to be hereinafter specifically referred to, claimed and illustrated inthe accompanying drawings, wherein: Figure 1 is a side elevation of a cutter head and blade constructed in accordance with my invention, one of the blades being shown in the act of engaging a length of wood. V

Figure 2 is an edge elevation of the device having parts broken away.

Figure 3 is a transverse sectional view taken on line 3 3 of Figure 1.

Figure 4l is an elevation of one'of the cutting blades.

Figure 5 is a similar view showing the reverse edge of the cutting blade.

Figure 6 is a side elevation of the cutting blade.

Referring to the drawings in detail wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 designates a disk or cutter head provided with substanthe grooves 10 is a cutter blade 13, while -tain the blades in position.

in the novel combination of elements, con! tially L-shaped in cross section and longi.

plates lllare disposed upon the opposite faces' of these vdisks or cutter heads and re- Bolts 15pass transversely through the plates and cutter head and are provided with nuts for holding the parts assembled.

In connection withrv the cutters I wish to emphasize that these cutters are of novel construction and that all of these cutters are Videntical and a detail description of one 05 will apply to all. This cutting blade is substantially arcuate shaped in configuration and comprises a web or body 16 having oppositely extending vflanges 17 and 18. The flange 18'is of less'size than the flange 17 70 but is approximately the same length and both of the flanges follow the curvature .of the web and extend at an angle from the web. As shown in Figure 3, the flange 18 isaccommodated in the base of the L-shaped groove l0 while the web 16 is accommodated Y within the other branch of the L-shaped groove as shown.

The plates or disks, 14 contact with the webV 16 and abut the in'- ner face of the flange 17. As illustrated in Figures 1, 5 and 6,*the inner face of the flange 17,v the outer face of the flange 18 and the inner face of the webI 16 of each blade isV beveled to the forward end of the blade as shown at 19, 20` and 21 respectively, and the forward edges of the flanges as shown'at 23 and 24: respectively are beveled at differ# ent angles from the forwardv ends of these flanges to the outer edges thereof while the forward edge of the web 16 is straight as shown at 25.

Due to the conguration .of these flanges and web it will be observed that the point of the cutter will be cutting while the heels are approaching the wood and emerging from the wood while the heels are still cutting and thereby avoiding the hammering of the cutting edges which is incident to blades havingA straight edges. Such ham-V mei-ing` would tend to jar the stock and thereby cause the latter to rough. Moreover, my type of cutter will throw the shavings to one side where the fans will carry them away. l A

Vhile I have shown and described the preferred embodiment of the invention, I, desire to have it understood that such changes may be made in the form, construction, arrangement of parts and operations, as Will not depart from the spirit of the invention or the scope of the subjoined comprising a rotatable cutter head having claims. longitudinal grooves in its opposite faces,

That is claimed is Y longitudinally curved cutting blades, each l5 l. A device of the character described of which comprising a web, a flange carried 5 comprising a body having substantially by one end and accommodated in the groove, L-shaped in cross section longitudinally a second flange extending from the web, the curved grooves, a Iblade in each groove inends of the anges being beveled in dii'ercluding a web, a flange carried thereby and ent planes and means for fastening the first 20 received in the groove, a second flange eX- mentioned anges in the grooves. 10 tending from the Web, the ends of such In testimony WhereofI aii'iX my signature.

flanges being beveled in dierent planes.
